I don't know the exact species but I have seen my trochus, astrea, and cerith snails eat it before. If you are up for a biological control method then I recommend them.
How old is that system @dragonfisher33 ? I have seen that a few times before, each time in systems <12 mos old. In one case, it was just a phase that passed. A couple of other tanks, we just dosed fluconazole (Flux) and it was gone in a week or so without any other casualties.
